ASSEMBLING-CRADLE To all whom it may concern p Be it known that I, CHARLES 'VV. OLSON, a

citizen of the United States, residin at De-' troit,in thecounty of Wayne and. gtate of Michigan, have invented a new and useful Improvement in Assembling-Cradles, of which the following is a specification; I

My invention relates to assembling cradles intended for use where assembling operations are performed on apparatus traveling along tracks or runways. My invention is particularly applicable to devices of this on the'bottom of the apparatus, my device is employed to receive the trucks orwheels carrying the apparatus; means are provided for clamping the apparatus in place on the cradle and then by releasing the locking devices with which'the cradle'is rovided, the

cradle andthe parts carried thereby maybe;

rotated substantially ninety degrees in which position they may be positively and safely held Without the danger of the apparatus falling from the oradleil By my invention I also provide devicesfor holding the cradle in its normal position for Whichtheapparatus passing along the runway may stop on the cradle if it is required to perform operationson the bottom of the apparatus, or this motion may be continued along the runway without interruption, if it is not necessary to use the cradle. a

My invention Will-best be understood by reference to the accompanying drawings showing a preferred'embodiment thereof in perspective view.

As shown in the drawings, tracks'l are shown in dotted lines as forming a part of a runway by which the apparatus may [be brought to the cradle, and tracks 2 are simi larly shown and form another part of the runway by'which the apparatusmay be removedfrom the cradle. The cradleconsists' Specification of Letters Patent.

v i Application filed February 16, 1920. Serial No. 358,987.

essentially'of parallel tracks 3, 3 mounted on circular frame members 4L 'and5 having outwardly projecting flanges 6 and7 which rest in grooved supporting rollers 8 and 9 respectively, said rollers being supported by bases 10 and 11 from the floor so as to bring the sectional tracks 3 into alinement-with the tracks 1 and 2. c

The framemembere is provided at 12 with holes through it to receive'the double locking bolt 13 pivotally connected at 14 with a foot lever 15. The lever 15 is pivotallyconnected at 16 with the back leg of the base 11, and projects through the frontleg of said base and terminates in a foot pad 17 in position for convenientoperation bythe workman. A spring 18 holds the-lever. 15 in its'upper position unless it isforcibly depressed. The front ends'of the flanges 6 and 7 are enlarged radiallvas indicated at 6 and Y, and forms stopsfor. engaging the front rollers 8 and 9 to prevent rotation of the cradle beyond its position of alinement with the tracksl andl2. The nlargement 7 a has projecting therefrom a pin 19 engaged by a latch 20. vpivotally supported at 21 on the housing of the front roller9, said lateh 20 being in the form of a bellcrank lever, the othervend ofwhich is pivotally connected with foot lever15, a link 22. :Whenthe lever 15 is in its uppermost position, the

latch 20 is in the position' indicated in the drawing to engage the pin 19 toprevent rotation of the cradle. I WVhen' it is desired i to rotate the" cradle,

the lever 15 is depressed, moving the locking bolt 13 from the holes12,and at the same time moving the latch 20 from engagement with the pin 19; For this condition, the cradle is "released 'and may be rotated on the rollers 8 and 9 until the enlarged ends 4 and 5 of the frame'members engage the back rollers Sand 9, which limitsttherotation of the cradle. At thistime' a secondpairi of looking holes 23 formed in the frame member 5'come into alinementf w'iththe locking bolt 13, and by engagement of the'loclring bolt therewith the cradle, may ,beheld in its rotated position as longas desired. The enlarged" ends and-5, may be of any desired sizeto serve as counterweightswhere the Workbeing assembledis of anature requiring some counterbalance to make the cradle easily rotatable when the apparatus being assembled is mounted. thereonl A rA E T .DFFICE, I

brace rod 24: is disposed between the upper ends of the members 4 and 5 to brace them and hold them in proper relation to each other. After the operations required have been performed on the bottom of the apparatus, the foot lever is depressed and the eradle is rotated to bring it to normal position with its two sections of track 3 in alinement with the stationary sections of track. lVhen the rotation of the cradle has brought the enlarged flanges 6 and 7 against the front rollers 8 and 9,. the latch 20 at once engages the pin 19 to prevent rebound of the cradle and also to prevent any tendency of the cradle to jump from the front rollers. The engagement of the latch 20 also serves to hold the cradle in positonso that the bolt 13 .may enter the locking holes 12 thus securing the cradle against rotation until its rotationis' again desired. j

In the drawing I have indicatedin dotted lines, diagrammatically a-motor 25 in position on the cradle, it being held in said positionby the rollers 26 so that it may be moved along the tracks to place the motor in position on the cradle. To hold the motor in the position indicated on the cradle, I prefer touse clamping devices as inclicated at 27 so as to prevent the motor or other work being assembled, from falling 01f the cradle when rotating. These clamps extend from under. the front rail 3 over any convenient part of the apparatus being assembled. I

While I have shown my invention in the particular embodiment abovedescribed, I do not however limit myself to this exact construction in carrying out my invention, as I may employ equivalents thereof known to the art at the time of the filing of this application without departing from the scope of the appended claims.

What I claim is:

combination of circular frame members, tracks secured to said frame members and extending between them, rollers supporting said members, and locking devices for holding said members in desired position on said rollers, said membershaving outwardly projecting flanges and said rollers having grooves engaging said flanges.

2. In a device of the class described, the combination of circular frame members, tracks secured to said frame members and extending between them, rollers supporting said members, and locking devices for bold in said membersindesired position on said ro lers, said locking devices comprising a foot lever, and a locking'bolt connected therewith and extending into one of said frame members.

3. In a device of the class described, the combination of circular frame members,
